I have been going to an obgyn for a few weeks now. I had a pap done and found that I have cervical cancer. I went back to get a biopsy done. She came in the room and said she couldn't proceed because my urine came back positive and I was 2 weeks pregnant. On my way home I stooped at CVS and got a clearblue home test which came back negative. So my question is why?... am I pregnant or not.
